HEATING-STOVE.

Specification of Letters Patent.

Application filed April 3, 1911.

Patented Mar. 5, 1912.

Serial No. 618,760.

To all whom it may concern:

Be it known that I, GEORGE L. MENK, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Heating-Stoves, of which the following is a specification.

This invention relates to heating stoves and has for its principal objects to secure a maximum radiation and circulation of heat from a minimum of fuel, to, humidify the atmosphere of the room heated by the stove, and to attain certain advantages hereinafter more fully appearing.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur, Figure 1 is a view, partly in side elevation and part-1y in vertical section, of

a stove arran ed for wood, coal or other carbonaceous fuel; Fig. 2 1s a vertical section on the line 2-2 of Fig. 1; Fig. 3 is a View, partly in side elevation and partly in;

vertical section, of a stove arranged for gas fuel; and Fig. 4; is a vertical section on the line 44 of Fig. 3.

Referring now, more particularly to Figs. 1 and 2 of the drawings, the upper portion of the stove comprises a horizontally disposed, substantially cylindrical heating drum or shell 1. The lower portion of thestove comprises a substantially rectangular shell 2. The fire-box 3 is located in the middle of the lower or base portion of the stove and vextends from end Wall to end wall. The grate 4 may be of any suitable or desirable construction, according to the fuel to be used. Beneath the grate 4 is an ashbox 5, access to which may be gained through a front opening 6 which is provided with a door 7. Obviously, the door 7 may be provided with any suitable draft openings and regulating device therefor. Fuel may be fed to the fire-box through the front opening 8 which is provided with a door 9.

The lower port-ions of the side walls 10 of the fire-box are preferably flared upwardly and the upper portions are turned inwardly, as at 11, to provide an elongated, restricted opening or slot 12 through which communication is established between the fire-boxor combustion chamber and the interior of the drum 1. Mounted in the drum, above the opening 12, is a baflie or spreader 13 which extends some distance on either side of the opening 12 and is preferably bent up on opposite sides from its middle, as shown. If desirable, an oven 14 may be mounted above the baflle 13, as shown; and, in some cases, the separate baffle 13 may be dispensed with and the bottom plate of the oven may obviously serve the purpose. In the rear wall of the drum, preferably near the top, as shown, is an outlet opening 15 which communicates with a flue or pipe 16 adapted to be connected in the usual manner with a draft flue, chimney or stack, as the case may be.

In the lower or base portion of the stove, on opposite sides of the fire-box, are air chambers 17 which are provided with a multiplicity of openings 18 in the bottoms thereof. The upper portions 19 of the air chambers are preferably flared, as shown, and covered with flat plates 20. A plurality of vertical tubes or flues 21 extend through the drum 1 on opposite sides of the bafiie 13 and oven 14. The lower ends of said tubes communicate with the upper portions 19 of the air chambers and the upper ends of the tubes are opened to the outside of the drum. Preferably, the drum is formed or constructed with reentrant portions 22, so as to provide fiat horizontal portions 23 into which the upper ends of the tubes 21 may be conveniently fitted.

In the lower portions of the air chambers 17 are placed water receptacles 24:- These receptacles are located next to the side walls 10 of the fire-box or combustion chamber, so as to be heated thereby; and said receptacles are preferably removable. For this purpose, shelves 25 are provided in the air chambers a slight distance above the bottoms thereof to support said water receptacles; and suitable doorways are, of course, provided either in the front or rear wall of the stove, through which the receptacles may be placed and removed.

The heated products of combustion from the chamber 3 pass through the elongated opening 12 and are deflected in opposite directions by the baffle 13, around the oven 14 and out through the opening 15 and line or pipe 16. As soon as the vertical flues being drawn in through the bottomopenings l8, initially heated in said chambers 17 by the heat radiated from the fire-box, and heated to a higher degree in the tubes 21. It is, therefore, obvious that inaddition to the extensive radiating surface of the drum, the circulation of heatedair thus created increases the efficiency of the stove. WVhen it is desirable to have a moist heat the receptacles 24 containing water are placed in the air chamber, as shown, and the evaporation causes the heated air which circulates out through the tubes 21 to become moisture laden.

In the construction illustrated in Figs. 3 and 1 of the drawings, the general arrangement is somewhat similar to the struc ture above set forth. In this modification, the stove is arranged for gas fuel. The combustion chamber 3 is provided with horizontal tubular gas fuel burners 26 which are provided with a multiplicity of jet openwith a plurality -of perforations 32 .on op-- posite sides near where it joins the base portion or lower shell 2*. The vertical air tubes .or fiues 21 open into the chamber 31 instead of .directly to the outside atmos phere as in the construction first set forth; and an elongated slot 33 is provided in the top of the drum 1 so that the products of combustion pass from the drum into the annular chamber 31. The baffle 13 and oven lt are arranged substantially the same as in the first mentioned construction. In this modification, also, the side air chambers 17 are eliminated and chambers 19 corresponding substantially to the before mentioned portions 19 of said air chambers 17, are substituted. The air inlet openings 18 in this case, are provided in the side Walls of the base portion 2*. Below the fuel burners in the combustion chamber 3*, and next to the side Walls thereof, are water receptacles 24. These receptacles are preferably removable, as in the case of .the before mentioned receptacles 24:. An addi tional water receptacle 24 is provided between said receptacles 24 and it is preferable to provide for placing said receptacle 24' at different heights with relation to the fuel burners. For this purpose, therefore, cleats or flanges 34 are provided on the receptacle 24 and lugs or flanges 35 are provided on the receptacles 24: adapted to reoeive said flanges 34. By changing the water receptacles 24c and 249 about, and in some cases, dispensing with one or more of them, the degree of the humidity may be varied. In this modification, the vapors arising from the water receptacle commingle with the products of combustion in the combustion chamber and heating drum .;and circulate therewith through. the outer The air which is drawninto chamber 31. the chamber 19 is heated in the vertical flues 21 and mixes with the vapors and products of combustion in the chamber 31. Nipples or tap tubes 36 are provided so that the drum 1 may be connected to suit able pipes or tubes to conduct off a portion of the products of combustion and vapors from the drum in cases, for example, where it is desirable to utilize the same for vapor baths and the like. Normally these tap tubes 36 are closed "by plugs or .othersuitable closures 37..

The drum portion of the stove is preferably constructed of sheet metal, 33S is .also the base portion. It is understood, however, that the fire-box may be suitably lined .according to the nature of the fuel used; and it is obvious that, in general construction, :the stove admits of considerable modification without departing from my -invention. Therefore, I do not wish to be limited to the specific constructions and arrangements having an outlet opening at its top communij eating with the space between said drum and outer shell, an air chamber directly adj-oining said fire-box and said -heating drum and being separated from each by a single wall,

said air chamber having air inlet open to the outside air, and a multiplicity of air tubes extending through said heating drum, said air tubes being non-communicating with respect to the heating drum, but communieating with said vair chamber and the space between said heating drum and said outer shell.

' 2. A heating stove comprising .a rectangular base shell, a heating drum mounted above said base shell .and communicating therewith spaced therefrom, said outer shell having outlet openings on opposite sides near the top of said base shell and said heating drum having an outlet opening at the top thereof communicating with the space between said drum and outer shell, a fire-box in said base shell, air chambers on opposite sides of the fire-box directly adjoining it and also directly adjoining said heating drum, said air chambers being separated from said fire-box and heating drum by single walls and having air inlets open to the outside air, and a multiplicity of vertical air tubes extending through said heating drum, said air tubes being non-communicating with respect to said heating drum, but communicating at their lower ends with the respective air chambers and at their upper ends with the space between said heating drum and said outer shell.

3. A heating stove comprising a fire-box, the upper portions of whose side walls are turned inwardly toward each other to provide an elongated contracted opening, a horizontally disposed heating drum mounted above 'said firebox and communicating therewith through said elongated contracted opening, an outer shell surrounding said heating drum and spaced therefrom, said outer shell having outlet openings on opposite sides of said heating drum near the bottom thereof and said heating drum having an outlet opening at the top thereof communicating with the space between said drum and the outer shell, air chambers on opposite sides of said fire-box directly adjoining it and also directly adjoining said heating drum, one of the walls of said air chambers comprising the side wall of said firebox and the other wall comprising the bottom of the heating drum, a multiplicity of vertical air tubes extending through said heating drum, said air tubes being non-communicating with respect to said heating drum, but communicating with the respective air chambers and also with the space between said heating drum and said outer shell.
